This chemical is an ideal replacement for Freon 22 detergent. Since no chiral center exists in this molecule, its chirality is due to the dissymmetric orientation of substituents about a chiral axis (the axis defined by the three carbon atoms of the double bonds). So hopefully it's obvious those are two rings and those are the bridgehead carbons that connect those two rings. Q:(c)) A partial character table for C3y point An object may be classified with respect to its symmetry elements or lack thereof. a Hydrogen selenide, H2Se b Partially deuterated hydrogen sulfide, or HDS c The chair conformer of cyclohexane, C6H12 d The boat conformer of cyclohexane, C6H12. Other low symmetry point groups are Cs (only a single plane of symmetry) and Ci (only a point of symmetry). Some of the symmetry elements of methane will be shown below by Clicking Here.
